James Shore, author of the book “The Art of Agile”, wrote an article that covers the alternatives to acceptance testing. The way you write an acceptance test is to take a user story and then write code that tests the end result of a software process. The acceptance test would only confirm that the website works by testing and checking user-visible changes. When it comes to testing, my goal is to eliminate defects. MORE
